Sec. 23.726 - Ground load dynamic tests.

(a) If compliance with the ground load requirements of 23.479 through 23.483 is shown dynamically by drop test, one drop test must be conducted that meets 23.725 except that the drop height must be --

(1) 2.25 times the drop height prescribed in 23.725(a); or
